Are groups more rational than individuals? A review of interactive decision making in groups
Kugler, Kausel and Kocher review the literature of the last twenty-five years on decision making by groups in interactive settings, where one party's outcome depends on the decisions of others. Standard game theory assumes selfish, perfectly calculating individuals, an assumption that many studies find problematic. Researchers have compared the strategic behaviour of groups and individuals in many games, including the prisoner's dilemma, dictator, ultimatum, trust, centipede and principal-agent games.
